Objectives: The objective of this study was to evaluate if the diastolic reserve is different in prediabetes versus control during exercise.
Materials And Methods: During the resting stage and graded supine bicycling exertion (25 W, 3 min increment), the mitral inflow and septal mitral annular velocities were determined in 50 patients with prediabetes (21 females, mean age 48 ± 16 years) and 50 gender- and age-matched controls. None demonstrated rest or inducible cardiac ischemia on echocardiography.
